Josiah grew up on a farm in central New Zealand to an engineer father and botanical artist mother, the youngest of five siblings. He picked up a film camera at a thrift store at the age of 14 and was instantly love-struck with how life looked rendered on celluloid. This discovery led him to to pursuing photography in high-school and later to study film production for four years afterwards. His final year project Inhabit, an 'artist in-residence' documentary gained a gold pin at the Best Awards and propelled Josiah into commercial film production, music videos and shorts. Outside of this, Josiah has assisted some of the worlds most celebrated director's and production companies in researching and writing for global brands and campaigns.

Josiah's work has a focus on stylistic naturalism and believes the craft of filmmaking is also the science of empathy, believing that every human is a vessel of infinite potential.
